Keysight Says AI Data Center Demand Is So Strong It Can't Keep Up, With Supply Constraints Masking True Order Strength
Fireside chat at Goldman Sachs Communacopia + Technology Conference, September 11, 2026
Keysight Technologies used its appearance at Goldman Sachs' Communacopia + Technology Conference to deliver a message that will resonate with investors trying to gauge the durability of AI-driven demand: the company is now supply-constrained, not demand-constrained, across a concentrated set of highly differentiated products feeding AI data center build-outs. CEO Satish Dhanasekaran and CFO Neil Dougherty, in conversation with Goldman analyst Mark Delaney, laid out a picture of orders that have topped $2 billion for two consecutive quarters, with management guiding revenue up to $1.94 billion in the fiscal fourth quarter, still trailing bookings by a meaningful margin.
Supply Constraints, Not Double-Ordering, Explain the Order-Revenue Gap
The most important new data point from the session was management's attempt to quantify the revenue being deferred due to supply constraints. Dougherty walked through the math: Keysight booked roughly $2.05 billion in orders in the second quarter, and under the company's normal six-month order acceptance window, that business should largely ship by the fourth quarter. Instead, Keysight has guided Q4 revenue to $1.94 billion, implying roughly $100 million of orders pushed beyond the normal shipment window. "I think $100 million is a way to kind of bound it at this point in time," Dougherty said, though he noted the practical number is likely smaller given deferred software revenue and longer-dated programs.
Both executives pushed back firmly on the idea that double-ordering is inflating the backlog, a concern that has dogged other test and measurement names amid the AI capex cycle. Dougherty was specific about the scope of the problem: constraints are concentrated in "20, 30 SKUs focused on this data center ecosystem," and those SKUs are differentiated enough that customers have no equivalent alternative to double-book. Dhanasekaran added that Keysight has visibility into demand not just from direct customers but through the broader ecosystem, "from likes of NVIDIA to their supply chain to what the hyperscalers are ordering," and that cancellation rates have historically been very low. The company is taking an 18-month view of its own supply chain and investing internally to close the gap, with Dhanasekaran saying he expects resolution "in a couple of quarters."
Wireline Has Quietly Overtaken Wireless Inside Communications Solutions
A structural shift inside Keysight's largest segment, Communications Solutions Group, got new visibility in this session. Wireline revenue, historically the smaller of the two components alongside wireless, has now surpassed wireless for the first time, driven almost entirely by AI infrastructure build-outs. Management had already disclosed that first-half AI revenue exceeded the full prior fiscal year, but Dhanasekaran went further, saying "the second half could be stronger than the first half from everything I see today." On the optical-versus-copper mix within AI interconnect, which represents just over a quarter of total company revenue, Dhanasekaran clarified that copper remains the predominant contributor today, with optical scaling as a longer-term opportunity, a data point that helps investors calibrate exposure to the NPO/CPO transition.
Hyperscaler Exposure Is Understated at 10% of Revenue
Dhanasekaran offered a figure investors have been asking for: direct hyperscaler revenue is sized at roughly 10% of total company mix this year. But he immediately qualified that this understates Keysight's true AI exposure, since hyperscalers exert significant downstream influence over their component and equipment supply chains that doesn't show up in direct billing relationships. "That number is actually a lot bigger," he said, pointing to design-cycle compression as adoption rates move from 100G to 400G to 800G networking speeds, with overlapping technology generations creating sustained tailwinds rather than a single step-function.
6G Investment Has Shifted From Research to Commercial Programs
Dhanasekaran flagged a tone shift in 6G conversations that he said prompted him to call it out on the recent earnings call. Three things changed simultaneously this year: standards work started gaining real traction, customer investment broadened beyond episodic university research into programmatic commitments from network equipment makers and chipset companies, and operator conversations moved from "let's talk about 6G later" to "let's discuss 6G." He pointed to 2028, the U.S. Olympics year, as an industry milestone the sector is building toward, and highlighted new technical dimensions in 6G, including higher frequencies and bandwidths, latency-sensitive non-terrestrial network applications, and Integrated Sensing and Communication, that expand Keysight's addressable emulation opportunity beyond what existed in 5G. Satellite broadband, while still described as "a smaller part of the portfolio," is being positioned as a complementary layer to terrestrial networks rather than a competing one, an architecture Dhanasekaran said plays directly to Keysight's Spirent-acquired satellite constellation simulation capabilities.
Defense Growth Increasingly Driven by Europe and Neo-Primes
Aerospace and defense revenue has grown year-over-year for seven consecutive quarters, and Dougherty offered a notable disclosure on geographic mix: "Europe has actually been the star. We've seen really strong growth in the U.S. and that strong growth in the U.S. has been outpaced by our growth in Europe this year." Dhanasekaran framed this as a durable, multi-year sovereign technology investment cycle rather than a temporary geopolitical response, alongside prime contractor capacity additions and the emergence of faster-moving "Neo-primes" that are less dependent on traditional government-funded bidding cycles.
Margin Trajectory on Spirent Integration Ahead of Plan
On capital allocation and integration economics, Dougherty confirmed the Spirent-related acquisitions, which were operating at low single-digit margins at the time of purchase roughly ten months ago, are on track to reach operating margins north of 30% as the company enters fiscal 2027, consistent with the corporate average. Synergy capture against the company's $100 million target has already reached 80% to 90%, ahead of schedule. Dougherty also flagged a technical modeling point for investors: fiscal 2026 incremental margins benefited from a one-time roughly $100 million cost reduction tied to a Supreme Court decision invalidating certain tariffs, meaning 2026 figures need to be normalized before applying the company's 40%-plus incremental margin framework to 2027.
